The renewable grid mix requirements for public electric utilities (and Xcel Energy) are 17% (25%) by 2016, 21.5% (31.5%) by 2020, and 26.5% by 2025.
Most utilities in Minnesota offer green power or green pricing programs whereby a city can purchase green tags (RECs, or Renewable Energy Credits) that assure additional renewable energy generating capacity is built.
Read about the 2016 Governmental Solar Garden Subscriber Collaborative, a joint effort by and for 31 local governments in the greater Twin Cities metropolitan region that procured solar garden subscriptions via a single Request for Proposals (RFP) process to offset the energy usage at public facilities. By working together, the participants sought to gain an economy of scale in the solicitation process that could help to attract developers, reduce the administrative burden to vet those developers, and yield better pricing and subscription terms. Cities used their B3 data to gauge the maximum amount of electricity they could subscribe to. In 2018 a similar joint purchasing program, Solar Possible, facilitated purchase of 4 MWs of solar PV systems, via a joint RFP and a master contract, by nearly a dozen cities/government units, with cost savings of 10-15%. See also the Midwest Renewable Energy Association's group-buy Solarize program.
Cities participating in the Cooperative Purchasing Venture membership with the State of Minnesota can purchase solar power system design and installation services on state contract release S-1049(5).
Third-party solar (see a model RFP and other documents) agreements have a city lease city-owned roof (or other) space to a company that installs & owns generating capacity used by the city. Or the city signs a power purchase agreement from generating capacity not on city property. Because a private company can take advantage of any state/federal tax credits, energy costs to the city are typically lower than the local utility rate.
Purchase above the renewable electricity grid mix required in state law: purchased renewable energy credits ("green tags") and/or a city government subscription of electricity from a community solar garden and/or a "third-party" agreement whereby the city leases roof (or other) space to a company that installs & owns generating capacity sold to the city. Report 'behind the meter' city-generated/used renewable energy under actions 1.7 or 20.6 or 22.5; report city promotion of resident/business purchases from a community solar garden under 26.4
Purchase electricity, natural gas, liquid fuels & steam heat such that in total the energy content of renewables makes up at least 35% of total city operations energy; report if municipal utility generation mix is above that required by MN law; report city council direction to its muni (via board appointments, annual goals/reports/funding) to accelerate work on city clean energy goals.
Purchase 100% renewable electricity for city operations from a solar garden, 3rd party, or via green tags; purchase electricity, natural gas, liquid fuels & steam heat such that in total energy content renewables make up at least 50%; join the Green Power Partnership.

Year action initially completed:
A ground-source, closed-loop geothermal system was installed in City Hall in 2012. In 2016, solar panels (capacity of 796,000 kWh) were installed on the roof of City Hall and the Veterans Memorial Community Center to supply energy to these buildings. The City also has 10 community solar contracts. Each contract is estimated to produce approximately 300,000 kWh for a total of 3,000,000 kWh annually.
On April 17, 2017, the City of Jordan’s City Council approved the city to move forward and finalize a contract with ReneSola – a community solar company. After that, the city will offset 120% of its electricity usage from a community solar garden, saving about $3,000,000 over the 25 year contract.
Outcome measures/metrics/money saved:
The cost savings associated with going solar, and the amount of carbon emissions eliminated, will ultimately be used to judge this action.
In 2017, the City of Minnetonka began purchasing electric energy from a solar garden (WGL Energy). In 2017, 32% of the City's full electric load was from 100% solar produced, and the remaining 68% of the energy usage was from 25% renewable.
Beginning in 2021, the City of Moorhead will be 100% carbon-free. Upon analyzing 2019 energy data from Missouri River Energy Services (MRES), Moorhead's supplementary energy provider, it was noted that Moorhead Public Service (MPS) was already 87% carbon-free, based upon energy generated from hydropower, solar, wind, and other carbon-free energy sources. Through MRES' Bright Energy Choices Program, MPS is purchasing renewable energy credits to cover the additional 13% of energy that is coming from carbon-based power resources.

On October 24, 2017, the Oakdale City Council authorized entering into a subscription agreement for the purchase of 4.68 million kWh of electricity annually from a community solar garden. This amount is 120% of the city's annual electricity usage in its operations.
Outcome measures/metrics/money saved:
Over the lifetime of the agreement, over 110 million kWh will be generated from a clean energy resource, which otherwise would produce 77,475 metric tons of GHG emissions. That is the equivalent amount of the annual emissions from 16,365 passenger vehicles. Additionally, the City will see a significant financial benefit from its participation.
The City of St. James receives its power from St. James Public Utility. Currently 9% of our electricity comes from wind resources and 63% is supplied by hydropower. Overall, renewable energy supplies 72% of total purchases by the City of St. James, 78% of the total power is carbon-free.
The city government receives its power from our Municipal Utility. 11% comes from our landfill gas plant, 1.5% comes from wind, and the remaining renewables come from hydropower in Manitoba and GRE's refuse-derived-fuel facility. Altogether, renewables account for about 20% of our energy needs.
The City of Marshall receives its power from Marshall Municipal Utility. Currently 15% of our electricity comes from wind resources and 17% is supplied by hydropower. Overall, renewable energy supplies 32% of total purchases by the City of Marshall.
Morris's electrical utility is Otter Tail Power Company, and they generate 20% of their energy through renewable sources.
Morris's UMN campus produces 60% of its energy with 2, 2 MW wind turbines, and Morris Area Schools are installing 8 kW of Solar in the Spring of 2019.
The City of Northfield has subscribed to a Community Solar Garden through CleanChoice Energy (originally MN Community Solar) as of August 2017. This subscription provides electricity for approximately 80% of the City buildings in Rice County. The WWTP is in Dakota County and was not eligible to be part of the subscription.
The city currently has 25-year deals with two different solar garden facilities; which will equate to 28.5% of city wide energy used by city government being generated by solar sources. In 2016 the city committed to the City Hall being powered completely by 3rd party solar energy (7.5% of city wide energy). The city is currently in the process of switching the Rec Center and Lily Lake Arena to 3rd party solar energy. Last month, in March 2019, the city started its first of two phases to switch over to solar power at these sites; and the second phase will commence this Fall, which will result in an additional 21% of city energy powered by solar.
Minnesota Three LLC's Solar Array is a collaborative effort between Freeborn-Mower Cooperative Services (Albert Lea), People's Energy Cooperative (Oronoco) and Tri-County Electric Cooperative (Rushford) to bring commercial-grade solar energy to southeastern Minnesota. The 517 kW solar array began generating electricity on June 30, 2014, and harvests enough of the sun's rays to power about 60 homes.
The City's utility Dakota Electric sources 20% of their electrical generation from renewables (hydro, wind, natural gas, and refuse derived.
In addition, the Apple Valley Liquor Store #3 is the first business in the state of Minnesota to receive a “Green Globe Award” for Outstanding Achievement in Environmental Stewardship.

The city's progressing solar energy project (installing solar panels on 5 city buildings - 4 of 5 projects have been approved by Xcel Energy with 1 still pending as of 8/13/12) will allow us to produce a lot of our own energy instead of needing to purchase energy at all, let alone from renewable sources.
The City of Rogers was recently awarded a grant to install solar panels at its Public Works facility. In the summer/fall of 2014, the City of Rogers Public Works building will have 210 silicon solar panels installed on its roof. The panels should generate enough energy to power the entire facility.
